System and method for providing an extensible codec architecture for digital images
First Claim
1. A computer system for performing imaging operations on a digital image, comprising:
- a processing unit;
executable software code for requesting an imaging operation to be performed on a digital image;
a codec manager operably coupled to the executable software code for receiving the request to perform an imaging operation on the digital image, discovering one or more imaging components for performing the imaging operation on the digital image, the imaging components including a plurality of operations that may be performed by the imaging components on the digital image, assigning a weight for each operation that may be performed by the imaging components on the digital image, and for selecting the imaging component from the plurality of imaging components that has a sum of weights assigned for each performable operation that is greater than the sum of weights assigned for each performable operation performable by another imaging component to perform the requested imaging operation on the digital image; and
a selected imaging component operably coupled to the codec manager, the selected imaging component having registered information in the computer system that may indicate that the selected imaging component may perform imaging operations on the digital image.

Abstract
An improved system and method for an extensible codec architecture for digital images is provided. Executable software code may be operably coupled to a codec manager for requesting imaging operations to be performed on a digital image. The codec manager may receive the request to perform an imaging operation on the digital image and may select an imaging component, such as a codec, from one or more imaging components registered in the computer system for performing an imaging operation on the digital image. An arbitration manager may include functionality for requesting enumeration of the operations an imaging component may perform on a particular digital image. One or more pixel format converters may then convert the pixel format in the digital image to a pixel format supported by an imaging component installed on the system.

19. A computer program product for implementing a method for providing an extensible codec architecture for digital images, the computer program product comprising one or more computer readable storage media storing thereon computer-executable instructions that, when executed by one or more processors of the computing system, cause the computing system to perform the method, the method comprising:
-
installing an imaging component in the computer system among a plurality of other imaging components, the imaging component allowing new image formats and new pixel formats for digital images to be flexibly added to the imaging component, the imaging component further allowing automatic conversion of new pixel image formats to pixel image formats that may be recognizable by other imaging components; registering the imaging component in the computer system so that the imaging component may be discovered among the plurality of imaging components for use in performing an imaging operation without having to instantiate the discovered imaging component; receiving a request for performing an imaging operation on a digital image; discovering the imaging component for performing the imaging operation on the digital image, the imaging component including a plurality of operations that may be performed by the imaging component on the digital image; assigning a weight for each operation that may be performed by the imaging component on the digital image; selecting an imaging component from the plurality of imaging components for performing the imaging operation on the digital image, wherein the selected imaging component has a sum of weights assigned for each performable operation greater than the sum of weights assigned for each performable operation performable by another of the plurality of imaging components; and using the selected imaging component for performing the imaging operation on the digital image. - View Dependent Claims (20)
